Optimum Tilt Angle For Solar Panels Sydney

Most australian homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation.

Optimum tilt angle for solar panels sydney.

Perth latitude 32º. Sydney latitude 34º. In every capital except darwin output is maximized when the solar panel tilt is at least a few degrees less than the latitude. To optimize overall production year round tilt your panels at your latitude.

However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss. To lean toward more production in the winter tilt your panels at your latitude plus 10 15. The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production. Both of these angles require latitude degrees.

Generally speaking unless your roof is flat the pitch of your home s roof is going to be the angle your solar panels are mounted at. There are two methods for calculating the tilt angle for solar panels. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer. For example if you reside in sydney a roof pitch of 34 would be considered ideal as this is equal to the latitude angle 33 86 of the nsw capital.

This means that for best results the roof pitch of your property should ideally be equal to the latitude angle with the panels mounted at the same angle as the roof.
